Corsair does not have its own power supply, it rebadge of other power supplies manufacturers, but contrary to what I read in a comment that is not the famous Seasonic that manufactures it but CWT (realhardtechx checked. com). This is not the golden opportunity to buy cheap Seasonic.
The big disappointing point of this power supply is the little noise it makes. It's not huge but it's annoying. When my records are in standby, the computer is completely silent ... except this power supply makes a rattling! is the fan I think. I do not know if it is a defect or if this is normal but from what I read I'm not the only one. However as soon as the discs come on we no longer hear the PSU. I take off even as two stars because it's just not normal for a fan to the low speed sound.
